Description

Speakers and headphones Technical Field

[0001] The present invention relates to the field of sound-to-electricity conversion, and in particular to a loudspeaker and an earphone with the loudspeaker. Background Art

[0002] A speaker is a transducer that converts electrical signals into acoustic signals. With the continuous advancement of science and technology, consumers have higher requirements for the sound quality of electronic devices.

[0003] Dynamic speakers are a common type of speaker and one of the most basic. They consist of two main components: a diaphragm and a driver. The diaphragm is typically a lightweight, circular membrane located at the front of the driver and connected to a bracket. The driver typically includes a magnetic circuit system and a coil. The magnetic circuit system is fixed to the rear of the sound chamber, while one end of the coil is fixed to the center of the diaphragm and the other end extends into the magnetic gap of the magnetic circuit system. When an AC signal passes through the coil, a strong magnetic field is generated around the coil. This magnetic field interacts with the magnetic field in the magnetic circuit system, generating a force that pushes the coil and diaphragm forward. When the direction of the current changes, the diaphragm also moves in the opposite direction. By varying the direction and magnitude of the electrical signal, periodic motion is generated in the diaphragm, producing sound. Dynamic speakers operate based on the principle of electromagnetic induction. Applying an electrical signal to the diaphragm generates an electromagnetic force that causes it to vibrate, thus producing sound. However, the diaphragm is typically made of plastic, which is flexible and prone to uneven vibration. This creates a greater force to agitate the airflow, resulting in a less pure sound.

[0054] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0055] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0056] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0057] Example 1:

[0058] Referring to Figures 1 to 7 , a speaker and headphones with a speaker according to a first preferred embodiment of the present invention are shown. The speaker 1 is an electroacoustic conversion device that can convert electrical energy into sound. The speaker 1 is suitable for use in electronic devices. In this application, the speaker 1 is used in headphones 2 as an example. It should be understood that although the speaker 1 is used in headphones 2 as an example, in other embodiments, the speaker 1 can be used in other fields and is not limited to this application.

[0059] For ease of explanation, in this embodiment, the end of the speaker 1 that vibrates and produces sound is referred to as the front end of the speaker 1, and the end opposite to the front end of the speaker 1 is referred to as the rear end of the speaker 1. The end of the earphone 2 that faces the wearer's ear canal when worn is referred to as the front end of the earphone 2, and the end opposite to the front end of the earphone 2 is referred to as the rear end of the earphone 2. When the speaker 1 is installed in the earphone 2, the front end of the speaker 1 and the front end of the earphone 2 are close to each other, and the speaker 1 has a high sound resolution, so that the earphone 2 has a better sound effect.

[0060] FIG1 is a schematic diagram of the overall structure of a speaker 1 according to a first preferred embodiment of the present invention. In this embodiment, the speaker 1 includes a speaker housing 10, a drive assembly 20, and a vibration sound-generating assembly 30. The drive assembly 20 and the vibration sound-generating assembly 30 are mounted on the speaker housing 10. When current flows through the drive assembly 20, the drive assembly 20 is adapted to drive the vibration sound-generating assembly 30 to vibrate and thereby emit sound.

[0061] The speaker housing 10 includes a main body 11 and a receiving cavity 12, wherein the receiving cavity 12 is provided in the main body, that is, the receiving cavity 12 extends from the front end of the main body 11 to the recess, and the driving assembly 20 and the vibration sound generating assembly 30 are installed in the receiving cavity 12. In this embodiment, the main body 11 is a component formed with the receiving cavity 12, for example, a bracket made by plastic injection molding technology.

[0062] FIG2 is a schematic diagram of the front structure of a loudspeaker according to a first preferred embodiment of the present invention. The vibration sound-generating component 30 includes a diaphragm body 31, the material of which can be a plastic material such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyetherimide (PEI), polyimide (PI), liquid crystal polymer (LCP), polyetheretherketone (PEEK), polycarbonate (PC), polyphenylene sulfide (PPS), polyarylate (PAR), etc.

[0063] The diaphragm body 31 is mounted on the speaker body. The driving assembly 20 includes a plate wire layer 33 and a permanent magnet 22. The plate wire layer 33 is attached to the surface of the diaphragm body 31. For example, the plate wire layer 33 is formed by etching a planar metal layer and adhered to the diaphragm body 31. In this embodiment, the circuits of the plate wire layer 33 are distributed in a ring shape on the diaphragm body 31, thereby forming a planar coil. In other words, the plate wire layer 33 includes a plurality of concentric circular circuits of different diameters. Based on this, the speaker 1 has a higher resolution by adhering a plate wire layer 33 to a diaphragm body 31 to form an integral body with the diaphragm body 31. When a driving current is passed through the plate wire layer 33, the magnetic field generated by it interacts with the magnetic field of the permanent magnet 22, so that the taut diaphragm body 31 is driven by the plate wire layer 33 to generate micro-vibration, thereby achieving excellent mid-frequency and high-frequency performance.

[0064] It should be understood that the speaker 1 of the present invention has a voice coil circuit 21 that is planar and flat. Its circuitry is formed within a single plane, unlike a traditional voice coil with a relatively high thickness. One end of the circuit is connected to the diaphragm, and the other end is coupled to the magnetic circuit system. The plate circuit layer 33 can be formed first and then attached to the diaphragm body 31. Alternatively, a plate circuit layer precursor, such as a metal layer, can be formed on the diaphragm body 31, and then the metal layer is formed into circuitry through subsequent processing steps such as etching to form the plate circuit layer 33.

[0065] In addition, the edge 310 where the diaphragm body 31 is connected to the speaker housing 10 is not provided with the circuit of the plate line layer 33, so that when the diaphragm body 31 vibrates, the vibration of the edge 310 thereof will not cause pulling on the circuit of the plate line layer 33 and cause damage to the circuit of the plate line layer 33.

[0066] It is worth mentioning that, as shown in FIG2 , the vibration sound-generating component 30 further includes a vibration plate 32, and the vibration plate 32 is arranged on the surface of the diaphragm body 31. The diaphragm body 31 has a center portion 311 and an edge portion 312. In this embodiment, the diaphragm body 31 is configured to be circular, based on which the edge portion 312 is integrally surrounded by the outer side of the center portion 311. The vibration plate 32 is mounted on the center portion 311 of the diaphragm body 31, such as being bonded to the center portion 31 of the diaphragm body 31. In other words, the vibration plate 32 is mounted on the central area of ​​the diaphragm body 31, and the plate line layer 33 is located around the vibration plate 32.

[0067] The vibrating plate 32 is made of a non-magnetic material, preferably a metal material, such as aluminum or copper, so that the permanent magnet 22 does not generate a magnetic attraction force on the vibrating plate 32. The central area of ​​the vibration sound generating component 30 has a thicker thickness to improve the bass quality of the speaker 1.

[0068] The vibration plate 32 can be in various shapes, and is preferably centrally symmetrically arranged on the surface of the diaphragm body 31. For example, the vibration plate 32 can be circular, square, etc. In this embodiment, the vibration plate 32 is annular. And in this embodiment, the vibration plate 32 is attached to the diaphragm body 31. In another modified embodiment, the central part of the surface of the diaphragm body 31 can also be attached to the plate line layer 33, so that the vibration plate 32 is attached to the plate line layer 33 of the diaphragm body 31. In another modified embodiment, the vibration plate 32 and the plate line layer 33 can be attached to opposite sides of the diaphragm body 31 respectively.

[0069] Therefore, the speaker 1 is provided with the vibration plate 32 on the surface of the diaphragm body 31. When the diaphragm body 31 is vibrated, the vibration plate 32 is driven to vibrate synchronously, producing a heavy, metallic bass effect, thereby improving the sound quality of the speaker 1, especially the low-frequency sound effect, and solving the problem that existing speakers cannot provide the low-frequency sound quality effect. In other words, the portion of the diaphragm body 31 with the vibration plate 32 vibrates together, having a larger vibration stroke and strengthening the bass effect, while the portion of the diaphragm body 31 without the vibration plate 32 produces micro-vibrations and provides mid- and high-frequency sound effects. Therefore, the speaker 1 can provide full-band sound effects, thereby improving the acoustic effect.

[0070] Compared to existing speakers, the plate wire layer 33 of the speaker 1 is attached to the diaphragm body 31 and forms an integral part with the diaphragm body 31. The plate wire layer 33 is lightweight and does not burden the vibration of the diaphragm body 31. The diaphragm body 31 is stretched tight, thereby reducing elastic buffering and micro-vibrations generated by current and magnetic field, thereby producing better sound effects. Furthermore, the permanent magnet 22 and the diaphragm body 31 are saved, making the speaker 1 more affordable and easier to promote. When the speaker 1 is installed in the earphone 2, the sound quality of the earphone 2 is improved while also reducing the price of the earphone 2.

[0071] The permanent magnet 22 is disposed in the accommodating cavity 12 of the speaker housing 10 . When current flows through the plate wire layer 33 , an electromagnetic effect is generated to produce an attraction and repulsion action with the permanent magnet 22 , thereby driving the diaphragm body 31 to vibrate and produce sound.

[0072] It is understood that the permanent magnet 22 does not need to form a magnetic gap like the magnetic circuit system of the existing dynamic coil speaker. The permanent magnet 22 can be a flat magnet such as a cylindrical magnet or a ring magnet, which only needs to provide a flat magnetic pole on the top surface.

[0073] FIG5 is a perspective cross-sectional view of a speaker according to a first preferred embodiment of the present invention. The main body 11 includes a front unit 111 and a rear unit 112, and the front unit 111 and the rear unit 112 are integrally connected. The accommodating cavity 12 is provided in the front unit 111 and the rear unit 112, that is, the front unit 111 and the rear unit 112 each form a portion of the accommodating cavity 12. The permanent magnet 22 is mounted on the rear unit 112 of the main body 11, and the diaphragm body 31 is provided on the front unit 111 of the main body 11.

[0074] In the embodiment of the present invention, the diaphragm body 31 is fixed to the front unit 111 of the main body 11 by bonding. Specifically, the outer periphery of the diaphragm body 31 is fixed to the inner wall of the front unit 111 of the main body 11. In other embodiments, the diaphragm body 31 can also be fixed to the front unit 111 of the main body 11 by other means. Those skilled in the art should understand that this is not a limitation of the present invention.

[0075] In this embodiment, the main body 11 is in a truncated cone shape, that is, the diameter of the front unit 111 of the main body 11 is larger than the diameter of the rear unit 112, and the rear unit 112 is integrally connected to the rear end of the front unit 111, that is, the rear unit 112 extends backward from the rear end of the front unit 111.

[0076] The main body 11 also has a front end face 113, a rear end face 114 and a connecting face 115. The front end face 113 is arranged at the front end of the front unit 111, the planar diaphragm 31 is arranged at the front end face 113, and the rear end face 114 is arranged at the rear end of the rear unit 112. The connecting face 115 is the connection between the front unit 111 and the rear unit 112, that is, the rear unit 112 protrudes backward from the connecting face 115.

[0077] FIG3 is a schematic diagram of the rear end structure of a speaker according to a first preferred embodiment of the present invention. The speaker 1 further includes a circuit control component 40, which is disposed on the main body 11, specifically, on the rear end surface 114 of the main body 11. The circuit control component 40 is electrically connected to the drive component 20, the vibration sound generating component 30, and an external circuit, such as the control circuit of the earphone 2.

[0078] The circuit control assembly 40 includes a first connection end 41, a second connection end 42, a first transmission end 43, a second transmission end 44, and a circuit module 45. The first connection end 41, the second connection end 42, the first transmission end 43, and the second transmission end 44 are all disposed on the circuit module 45, which is disposed on the rear end surface 114 of the main body 11. The first connection end 41 and the second connection end 42 are adapted to be electrically connected to the board wiring layer 33 via wires to transmit current to the board wiring layer 33. The first transmission end 43 and the second transmission end 44 are adapted to be electrically connected to the control circuit of the earphone 2 via wires.

[0079] Figure 7 is a structural diagram of a speaker installed in an earphone according to the first preferred embodiment of the present invention. In this embodiment, the speaker 1 can be installed in a traditional earphone, so that the traditional earphone has higher resolution, excellent mid-frequency and high-frequency performance, obvious bass effect, and better sound quality. The earphone 2 includes an earphone main body 50 and a speaker 1, and the speaker 1 is suitable for being installed in the earphone main body 50. The earphone main body 50 includes a sound-emitting part 51 and a fixing part 52, the fixing part 52 is connected to the sound-emitting part 51, the sound-emitting part 51 is suitable for being placed in the wearer's ear, and the fixing part 52 is suitable for being fixed to the outside of the wearer's ear, so that the earphone 2 can be firmly fixed to the wearer's ear.

[0080] The sound-emitting portion 51 has a mounting cavity 511, and the speaker 1 is adapted to be mounted within the mounting cavity 511. When the speaker 1 is mounted within the earphone 2, the front end of the speaker 1 and the front end of the earphone 2 are close to each other. In other words, the front end surface 113 of the speaker 1, where the diaphragm body 31 is located, is close to the front end of the earphone 2, allowing the sound produced by the earphone 2 to better enter the wearer's ear canal and improve the sound quality of the earphone 2. The rear end surface 114 of the speaker 1, where the circuit module 45 is located, is close to the rear end of the earphone 2, facilitating electrical connection between the speaker 1 and the earphone body 50.

[0081] The following is an exemplary introduction to the assembly method of the earphone 2.

[0082] A: forming a speaker housing 10;

[0083] B: attaching a plate wire layer 33 to an edge portion 312 of a diaphragm body 31 and fixing the diaphragm body 31 to a front unit 111 of the speaker housing 10;

[0084] C: Installing a vibration plate 32 on a central portion 311 of the diaphragm body 31;

[0085] D: Installing a permanent magnet on a rear unit 112 of the speaker housing 10 and installing a circuit control component 40 on a rear end surface of the speaker housing to complete the assembly of a speaker 1; and

[0086] E: Install the speaker 1 in a sound-emitting portion 51 of an earphone body 50 to complete the assembly of the earphone 2.

[0087] In step A, when a speaker housing 10 is formed, specifically, the speaker housing 10 includes a main body 11 and a receiving cavity 12 , and the receiving cavity 12 is disposed in the main body 11 .

[0088] Among them, in step B, the plate wire layer 33 is formed by etching a metal layer, and the plate wire layer is attached to the edge portion 312 of the diaphragm body 31, and the diaphragm body 31 is fixed to a front unit 111 of the main body 11 of the speaker housing 10. Specifically, the plate wire layer 33 is integrated with the diaphragm body 31, and the weight of the plate wire layer 33 is relatively small, so it will not burden the vibration of the diaphragm body 31. The diaphragm body 31 is tightened, thereby reducing elastic buffering and micro-vibrations generated by current and magnetic field, thereby producing better mid- and high-frequency sound effects. In addition, the outer periphery of the diaphragm body 31 is fixed to the inner wall of the front unit 111 of the main body 11, and can be fixed by gluing or other methods.

[0089] In step C, a vibration plate 32 is mounted on a central portion 311 of the diaphragm body 31. Specifically, the speaker 1 is provided with the vibration plate 32 on the surface of the diaphragm body 31. When the diaphragm body 31 is vibrated, the vibration plate 32 is driven to vibrate synchronously, producing a heavy, metallic bass effect, thereby improving the low-frequency sound quality of the earphones.

[0090] In step D, a permanent magnet 22 is mounted on a rear unit 112 of the speaker housing 10, and a circuit control component 40 is mounted on a rear end surface of the speaker housing 10, thereby completing the assembly of the speaker 1. Specifically, the circuit control component 40 is electrically connected to the drive component 20, the vibration sound generating component 30, and an external circuit, such as the control circuit of the earphone 2.

[0091] In step E, the speaker is installed in a sound-emitting portion 51 of an earphone body 50, thereby completing the assembly of the earphone 2. Specifically, the speaker 1 can be installed in the earphone 2, so that the earphone 2 has higher resolution, excellent mid-frequency and high-frequency performance, obvious bass effect, and better sound quality.

[0092] Example 2:

[0093] Figures 8 to 11 are schematic diagrams of the overall structure of the speaker 1 according to a second preferred embodiment of the present invention. In this embodiment, the speaker 1 includes a speaker housing 10, a drive assembly 20, and a vibration sound-generating assembly 30. The drive assembly 20 and the vibration sound-generating assembly 30 are mounted on the speaker housing 10. When current flows through the drive assembly 20, the drive assembly 20 is suitable for driving the vibration sound-generating assembly 30 to vibrate and emit sound.

[0094] The speaker housing 10 includes a main body 11 and a receiving cavity 12, wherein the receiving cavity 12 is provided in the main body, that is, the receiving cavity 12 extends from the front end of the main body 11 to the recess, and the driving assembly 20 and the vibration sound generating assembly 30 are installed in the receiving cavity 12. In this embodiment, the main body 11 is a component formed with the receiving cavity 12, for example, a bracket made by plastic injection molding technology.

[0095] The vibration sound-generating component 30 includes a diaphragm body 31 and a voice coil 34. The voice coil 34 is connected to the diaphragm body 31. The material of the diaphragm body 31 can be plastic materials such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyetherimide (PEI), polyimide (PI), liquid crystal polymer (LCP), polyetheretherketone (PEEK), polycarbonate (PC), polyphenylene sulfide (PPS), and polyarylate (PAR).

[0096] The drive assembly 20 includes a magnetic return system 23, which comprises a permanent magnet 231, a pole plate 232, and an iron core 233, forming a magnetic gap 234. The pole plate 232 and the iron core 233 respectively contact opposite magnetic poles of the permanent magnet 231. A voice coil 34 is connected to the diaphragm body 31 at one end and extends into the magnetic gap 234 at the other end. When a driving current is input to the voice coil 34, the electromagnetic field generated by it interacts with the magnetic field of the magnetic return system 23, driving the voice coil 34 to reciprocate, thereby driving the diaphragm body 31 to vibrate and produce sound.

[0097] The vibration sound-generating component 30 also includes at least one plate wire layer 33, and the plate wire layer 33 is attached to the surface of the diaphragm body 31. For example, the plate wire layer 33 is formed by a planar metal layer through an etching process and adhered to the diaphragm body 31. In this embodiment, the circuits of the plate wire layer 33 are distributed in a ring shape on the diaphragm body 31, thereby forming a planar circuit. That is to say, the plate wire layer 33 includes a plurality of concentric circular circuits 331 of different diameters and arranged at intervals from each other. Based on this, the loudspeaker 1 has a higher resolution by adhering a plate wire layer 33 to a diaphragm body 31 to form an integral body with the diaphragm body 31. When a driving current is passed through the plate wire layer 33, the magnetic field generated by it interacts with the magnetic field of the permanent magnet 22, so that the taut diaphragm body 31 is driven by the plate wire layer 33 to generate micro-vibration, thereby achieving excellent mid-frequency and high-frequency performance.

[0098] The plate wire layer 33 can be first formed and then attached to the diaphragm body 31, or a plate wire layer precursor, such as a metal layer, can be first formed on the diaphragm body 31, and then the metal layer is formed into a circuit through a subsequent processing step such as etching to form the plate wire layer 33. In this embodiment, the plate wire layer 33 is not used to input a driving current. The speaker is integrated with the diaphragm body 31 through the plate wire layer 33 to increase the rigidity of the vibration sound-generating component 30 and reduce the elasticity, so that the sound effect emitted by the vibration is purer, the sound directionality is better, and the sound quality effect is improved, especially the mid-high frequency is better.

[0099] In addition, the edge 310 where the diaphragm body 31 is connected to the speaker housing 10 is not provided with the circuit of the plate line layer 33, so that when the diaphragm body 31 vibrates, the vibration of the edge 310 thereof will not cause pulling on the circuit of the plate line layer 33 and cause damage to the circuit of the plate line layer 33.

[0100] It is worth mentioning that, as shown in Figures 8 and 10, the vibration sound-generating component 30 further includes a vibration plate 32, which is arranged on the surface of the diaphragm body 31. The diaphragm body 31 has a center portion 311 and an edge portion 312. In this embodiment, the diaphragm body 31 is configured to be circular, based on which the edge portion 312 is integrally surrounded by the outer side of the center portion 311. The vibration plate 32 is mounted on the center portion 311 of the diaphragm body 31, such as being bonded to the center portion 311 of the diaphragm body 31. In other words, the vibration plate 32 is mounted on the central area of ​​the diaphragm body 31.

[0101] The vibrating plate 32 is made of a non-magnetic material, preferably a metal material, such as aluminum or copper, so that the permanent magnet 22 does not generate a magnetic attraction force on the vibrating plate 32. The central area of ​​the vibration sound generating component 30 has a thicker thickness to improve the bass quality of the speaker 1.

[0102] The vibration plate 32 can be in various shapes, and is preferably centrally symmetrically arranged on the surface of the diaphragm body 31. For example, the vibration plate 32 can be circular, square, etc. In this embodiment, the vibration plate 32 is annular and has a central through hole 321. And in this embodiment, the vibration plate 32 is attached to the diaphragm body 31. In another modified embodiment, the central part of the surface of the diaphragm body 31 can also be attached to the plate wire layer 33, so that the vibration plate 32 is attached to the plate wire layer 33 of the diaphragm body 31. In another modified embodiment, the vibration plate 32 and the plate wire layer 33 can be attached to opposite sides of the diaphragm body 31 respectively. It can be understood that the vibration plate 32 can be bonded to the diaphragm body 31, and can also be bonded to the plate wire layer 33, so as to be connected to the diaphragm body 31 through the plate wire layer 33. In this embodiment, the two plate wire layers 33 are disposed on opposite sides of the diaphragm body 31 , and the plate wire layers 33 and the voice coil 34 are respectively bonded to the two plate wire layers 33 .

[0103] Therefore, the speaker 1 is provided with the vibration plate 32 on the surface of the diaphragm body 31. When the diaphragm body 31 is vibrated, the vibration plate 32 is driven to vibrate synchronously, producing a heavy, metallic bass effect, thereby improving the sound quality of the speaker 1, especially the low-frequency sound effect, and solving the problem that existing speakers cannot provide the low-frequency sound quality effect. In other words, the portion of the diaphragm body 31 with the vibration plate 32 vibrates together, having a larger vibration stroke and strengthening the bass effect, while the portion of the diaphragm body 31 without the vibration plate 32 produces micro-vibrations and provides mid- and high-frequency sound effects. Therefore, the speaker 1 can provide full-band sound effects, thereby improving the acoustic effect.

[0104] Compared with existing speakers, the plate wire layer 33 of the speaker 1 is attached to the diaphragm body 31 and forms a whole with the diaphragm body 31. The weight of the plate wire layer 33 is relatively small, so it will not burden the vibration of the diaphragm body 31. The diaphragm body 31 is stretched, thereby reducing elastic buffering and micro-vibrations generated by current and magnetic field, thereby producing better sound effects.

[0106] Appendix 12 illustrates a third preferred embodiment of the present invention, providing an earphone 2A with a speaker. This preferred embodiment is a modified version of the first preferred embodiment. Compared to the first preferred embodiment, in this embodiment, the speaker 1A is incorporated into the earphone 2A, and the earphone 2A is implemented as a clip-on earphone. This results in higher resolution, excellent mid- and high-frequency performance, and pronounced bass, resulting in superior sound quality.

[0107] In the present embodiment, the loudspeaker 1A includes a loudspeaker housing 10A, a drive assembly 20A, a vibration sound-generating assembly 30A, and a circuit control assembly 40A. The drive assembly 20A and the vibration sound-generating assembly 30A are installed in the loudspeaker housing 10A. When current flows through the drive assembly 20A, the drive assembly 20A is suitable for promoting the vibration sound-generating assembly 30A to vibrate and then emit sound. The circuit control assembly 40A is arranged in the loudspeaker housing 10A, and the circuit control assembly 40A is electrically connected to the drive assembly 20A, the vibration sound-generating assembly 30A, and an external circuit, such as the control circuit of the earphone 2A.

[0108] The vibration sound-generating assembly 30A includes a diaphragm body 31A and a vibrating plate 32A. The driving assembly 20A includes a plate wire layer 33A and a permanent magnet 22A. The vibrating plate 32A is disposed on the surface of the diaphragm body 31A, and the plate wire layer 33A is attached to the surface of the diaphragm body 31A. In this embodiment, the plate wire layer 33A is distributed in a ring shape on the diaphragm body 31A. In other words, the plate wire layer 33A comprises multiple concentric circular circuits of varying diameters.

[0109] Figure 12 is a schematic diagram of a speaker mounted on an earphone according to a third preferred embodiment of the present invention. The speaker 1A can be installed in an earphone, resulting in higher resolution, excellent mid- and high-frequency performance, pronounced bass, and enhanced sound quality. The earphone 2A includes an earphone body 50A and a speaker 1A, which is adapted to be mounted within the earphone body 50A. The earphone body 50A includes a sound-emitting portion 51A, a fixing portion 52A, and a connecting portion 53A. The connecting portion 53A is connected to the sound-emitting portion 51A and the fixing portion 52A at both ends. The sound-emitting portion 51A is adapted to be placed within the wearer's cavum conchae. The fixing portion 52A is adapted to fit against the back of the wearer's ear, such as the back of the helix or earlobe. The wearer's helix is ​​secured within the area formed by the connecting portion 53A, allowing the earphone 2A to be securely clamped to the wearer's ear.

[0110] The sound-emitting portion 51A has a mounting cavity 511A, and the speaker 1A is adapted to be mounted within the mounting cavity 511A. When the speaker 1A is mounted within the earphone 2A, the front end of the speaker 1A and the front end of the earphone 2A are positioned adjacent to each other. In other words, the front end surface 113A of the speaker 1A, where the diaphragm body 31A is located, is positioned adjacent to the front end of the earphone 2A, allowing the sound produced by the earphone 2A to better enter the wearer's ear canal and improve the sound quality of the earphone 2A. The rear end of the speaker 1A is positioned adjacent to the rear end of the earphone 2A, facilitating electrical connection between the speaker 1A and the earphone body 50A.

[0111] Example 4:

[0112] Figure 13 illustrates a speaker 1B provided in accordance with a fourth preferred embodiment of the present invention. In this embodiment, the speaker 1B comprises a speaker housing 10B, a drive assembly 20B, and a vibration sound-generating assembly 30B. The drive assembly 20B and the vibration sound-generating assembly 30B are mounted on the speaker housing 10B. When current flows through the drive assembly 20B, the drive assembly 20B is adapted to drive the vibration sound-generating assembly 30B to vibrate and thereby generate sound.

[0113] The speaker housing 10B includes a main body 11B and a receiving chamber 12B. The receiving chamber 12B is disposed within the main body, that is, the receiving chamber 12B extends from the front end of the main body 11B toward the recess. The drive assembly 20B and the vibration sound generating assembly 30B are mounted within the receiving chamber 12B. In this embodiment, the main body 11B is a component formed with the receiving chamber 12B, such as a bracket made using plastic injection molding technology.

[0114] The vibration sound-generating assembly 30B includes a diaphragm 31B, a voice coil 34B, and an elastic suspension 35B. The voice coil 34B is connected to the diaphragm 31B. The diaphragm 31B can be made of a plastic material such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyetherimide (PEI), polyimide (PI), liquid crystal polymer (LCP), polyetheretherketone (PEEK), polycarbonate (PC), polyphenylene sulfide (PPS), or polyarylate (PAR). The elastic suspension 35B surrounds the diaphragm 31B to limit the vibration direction of the diaphragm 31B and prevent it from shaking or deflecting.

[0115] The driver assembly 20B includes a magnetic return system 23B, which comprises a permanent magnet 231B, a pole plate 232B, and an iron core 233B, forming a magnetic gap 234B. The pole plate 232B and the iron core 233B respectively contact opposite magnetic poles of the permanent magnet 231B. A voice coil 34B is connected to the diaphragm body 31B at one end and extends into the magnetic gap 234B at the other end. When a driving current is applied to the voice coil 34B, the electromagnetic field generated by it interacts with the magnetic field of the magnetic return system 23B, driving the voice coil 34B to reciprocate, thereby driving the diaphragm body 31B to vibrate and produce sound.

[0116] The vibration sound-generating component 30B also includes at least one reinforcing rib layer 39B, and the reinforcing rib layer 39B is attached to the surface of the diaphragm body 31B. Preferably, the reinforcing rib layer 39B is formed on the surface of the diaphragm body 31B by a concave-convex embossing process to implement a plurality of reinforcing rib units 391B, and the top surfaces of these reinforcing rib units 391B can be coplanar or non-coplanar. In this embodiment, preferably, the reinforcing rib unit 391B is set to a regular hexagonal structure, and two adjacent reinforcing rib units 391B share a side, that is, two adjacent reinforcing rib units 391B fit together, so that the plurality of reinforcing rib units 391B form a honeycomb structure, which increases the rigidity of the diaphragm body 31B and the body formed by the reinforcing rib layer 39B, thereby making the vibration response speed faster and the generated vibration directionality stronger, so that the sound resolution is high, and the recorded sound can be restored as realistically as possible, producing a high-fidelity sound quality effect that reaches the monitoring level.

[0117] In other possible implementations, the reinforcing rib unit 391B can also be set to a triangular structure, a quadrilateral structure or a pentagonal structure, etc. In other words, the reinforcing rib unit 391B is implemented by a concave-convex embossing process to form triangular reinforcing ribs, quadrilateral reinforcing ribs, pentagonal reinforcing ribs, etc., which are attached to the surface of the diaphragm body 31B. In this regard, those skilled in the art should understand that the shape of the reinforcing rib layer 39B is not a limitation of the present invention.

[0118] Compared to existing speakers, the rib layer 39B of speaker 1B is attached to the diaphragm body 31B and forms an integral part of the diaphragm body 31B. The rib layer 39B is lightweight, thus not burdening the vibration of the diaphragm body 31B. The diaphragm body 31B is stretched tight, reducing elastic buffering and microvibrations generated by current and magnetic fields, thereby producing better sound effects. Furthermore, the rib layer 39B increases the rigidity of the diaphragm body 31B and the rib layer 39B, resulting in faster vibration response and more directional vibration.

[0119] The reinforcing rib layer 39B can be formed first and then attached to the diaphragm body 31B, or a precursor, such as a metal layer, can be formed on the diaphragm body 31B first, and then the reinforcing rib layer 39B is formed through subsequent processing steps. In this embodiment, the reinforcing rib layer 39B is not used to input the driving current. The speaker is integrated with the diaphragm body 31B through the reinforcing rib layer 39B to increase the rigidity of the vibration sound-generating component 30B and reduce the elasticity, so that the sound effect emitted by the vibration is purer, the sound directionality is better, and the sound quality effect is improved, especially the mid-high frequency is better.

[0120] In addition, the edge 310B where the diaphragm body 31B is connected to the speaker housing 10B is not provided with the structure of the reinforcing rib layer 39B, so that when the diaphragm body 31B vibrates, the vibration of the edge 310B thereof will not cause pulling on the circuit of the reinforcing rib layer 39B and cause damage to the circuit of the reinforcing rib layer 39B.

[0121] Embodiment 5:

[0122] As shown in Figure 14, in this embodiment, the vibration sound-generating component 30B may further include a vibration plate 32B, and the vibration plate 32B is arranged in the center of the surface of the diaphragm body 31B. The diaphragm body 31B has a center portion 311B and an edge portion 312B. In this embodiment, the diaphragm body 31B is configured to be circular, based on which the edge portion 312B is integrally surrounded by the outer side of the center portion 311B. The vibration plate 32B is installed in the center portion 311B of the diaphragm body 31B, such as being bonded to the center portion 311B of the diaphragm body 31B. That is, the vibration plate 32B is installed in the central area of ​​the diaphragm body 31B. The reinforcing rib layer 39B is arranged around the center portion 311B of the diaphragm body 31B.

[0123] The vibrating plate 32B is made of a non-magnetic material, preferably a metal material such as aluminum or copper, so that the permanent magnet 22B does not exert a magnetic attraction force on the vibrating plate 32B. The central area of ​​the vibration sound-generating component 30B has a thicker thickness to improve the bass quality of the speaker 1B.

[0124] The vibration plate 32B can be in various shapes, and is preferably centrally symmetrically arranged on the surface of the diaphragm body 31B. For example, the vibration plate 32B can be circular, square, etc. In this embodiment, the vibration plate 32B is annular and has a central through hole 321B. And in this embodiment, the vibration plate 32B is attached to the diaphragm body 31B. In another modified embodiment, the central part of the surface of the diaphragm body 31B can also be attached to the reinforcing rib layer 39B, so that the vibration plate 32B is attached to the reinforcing rib layer 39B of the diaphragm body 31B. In another modified embodiment, the vibration plate 32B and the reinforcing rib layer 39B can be attached to opposite sides of the diaphragm body 31B respectively. It can be understood that the vibration plate 32B can be bonded to the diaphragm body 31B, or bonded to the reinforcing rib layer 39B, so as to be connected to the diaphragm body 31B through the reinforcing rib layer 39B. In one embodiment, the two reinforcing rib layers 39B are disposed on opposite sides of the diaphragm body 31B, and the moving plate 32B and the voice coil 34B are respectively bonded to the two reinforcing rib layers 39B.

[0125] Therefore, the speaker 1B is provided with the diaphragm 32B on the surface of the diaphragm 31B. When the diaphragm 31B is vibrated, the diaphragm 32B is driven to vibrate synchronously, producing a heavy, metallic bass effect. This improves the sound quality of the speaker 1B, especially the low-frequency sound effect, solving the problem that existing speakers cannot provide low-frequency sound quality. In other words, the portion of the diaphragm 31B with the diaphragm 32B vibrates together, resulting in a larger vibration stroke and strengthening the bass effect. The portion of the diaphragm 31B without the diaphragm 32B produces micro-vibrations and provides mid- and high-frequency sound effects. As a result, the speaker 1B can provide sound effects across the full frequency range, improving the acoustic quality.

[0126] Example 6:

[0127] As shown in Figure 15, in this embodiment, the vibration sound-generating component 30B includes a diaphragm body 31B, a voice coil 34B, an elastic suspension 35B, a plate wire layer 33B and a reinforcing rib layer 39B, wherein the plate wire layer 33B and the reinforcing rib layer 39 can be formed integrally on the diaphragm body 31B.

[0128] The plate line layer 33B includes a plurality of heart circle lines 331B, which can be first formed and then attached to the diaphragm body 31B, or a plate line layer precursor, such as a metal layer, can be first formed on the diaphragm body 31B, and then the metal layer is formed into a line through subsequent processing steps such as etching to form the plate line layer 33B. In this embodiment, the plate line layer 33B is not used to input the driving current. The speaker is integrated into the diaphragm body 31B through the plate line layer 33B to improve the rigidity of the vibration sound-generating component 30B and reduce the elasticity, so that the sound effect emitted by the vibration is purer, the sound directionality is better, and the sound quality effect is improved, especially the mid-high frequency is better. The reinforcing rib layer 39B is attached to the surface of the diaphragm body 31B and connected to the plate line layer 33B. Preferably, the reinforcing rib layer 39B is formed on the surface of the diaphragm body 31B by a concave-convex embossing process to be implemented as a plurality of reinforcing rib units 391. The plate line layer 33B and the reinforcing rib layer 39B may also be formed integrally and then attached to the diaphragm body 31B.
